This specification covers gabions and gabion mattresses produced from metallic-coated welded wire fabric, and metallic-coated wire for spiral binders, lacing wire, and stiffeners used to assemble the product. The material shall conform to the required values of tensile strength, weld shear strength, panel-to-panel joint strength. Salt spray and ultraviolet exposure tests shall be performed wherein the PVC coating shall conform to the required values of specific gravity, tensile strength, elastic modulus, hardness, brittleness temperature and resistance to abrasion.1.1 This specification covers gabions and gabion mattresses produced from metallic-coated welded wire fabric, and metallic-coated wire for spiral binders, lacing wire, and stiffeners used to assemble the product. The metallic-coated fabric may be polyvinyl chloride (PVC) coated after fabrication. The spiral binders, lacing wire, and stiffeners may be PVC coated after metallic coating. Polyvinyl chloride hereinafter will be designated as PVC.1.2 Welded wire fabric for gabions and gabion mattresses is produced in five styles, based on the kind of coating, as described in Section 4.1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.1.4 This specification references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this specification.1.5 The following safety hazards caveat pertains only to the test methods portion, Section 13, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 The methods in this guide can be used for screening of fabric softener products or to evaluate their performance, through a single cycle or multiple accumulative cycles, relative to a designated reference product or a comparative product(s).5.2 A single assessment of each of the product characteristics tested by these methods will not predict overall performance of the softener product. A single test run under specified fixed conditions cannot be expected to reflect the comparative performance under many other possible conditions of use.1.1 This guide evaluates the performance characteristics of fabric softener products. It provides guidance for evaluating the on fabric efficacy of treatment chemicals dosed into the wash, rinse, or dryer cycle in a home laundry washer or dryer. This guide can be used for screening of fabric softener products, or to evaluate the products through multiple accumulative cycles.1.2 The relative ranking of products assessed by these procedures may be affected by such factors as machine type and settings, fabric load composition, as well as by the washing and drying procedures used.1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 This test method determines the effectiveness of UVGI devices for reducing viable microorganisms deposited on carriers.5.2 This test method evaluates the effect soiling agents have on UVGI antimicrobial effectiveness.5.3 This test method determines the delivered UVGI dose.1.1 This test method defines test conditions to evaluate ultraviolet germicidal irradiation (UVGI) light devices (mercury vapor bulbs, light-emitting diodes, or xenon arc lamps) that are designed to kill/inactivate influenza virus deposited on inanimate carriers.1.2 This test method defines the terminology and methodology associated with the ultraviolet (UV) spectrum and evaluating UVGI dose.1.3 This test method defines the testing considerations that can reduce UVGI surface kill effectiveness (that is, soiling).1.4 Protocols for adjusting the UVGI dose to impact the reductions in levels of viable influenza virus are provided (Annex A1).1.5 This test method does not address shadowing.1.6 The test method should only be used by those trained in microbiology and in accordance with the guidance provided by Biosafety in Microbiological and Biomedical Laboratories.21.7 This test method is specific to influenza viruses1.8 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.9 Warning—Mercury has been designated by many regulatory agencies as a hazardous substance that can cause serious medical issues. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. Use caution when handling mercury and mercury-containing products. See the applicable product Safety Data Sheet (SDS) for additional information. The potential exists that selling mercury or mercury-containing products, or both, is prohibited by local or national law. Users must determine legality of sales in their location.1.10 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.11 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

1.1 This test method covers measuring the thickness of the coating over fiber backing or reinforcing fabric.1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.1.3 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
